Consider the genealogy of six haploid individuals in the left upper corner of the figure. Substitution events are depicted as circles for a total of five loci. Which of the five site-frequency-spectra best corresponds to the data?
E
Which of the following is not a reason that an effective population size can be smaller than the
actual population size?
Every individual produced exactly two offspring
You genotype a biallelic locus in a very small population of only two chromosomes (N=2) and find
that both alleles are present. What is the probability that in two generations, both alleles are still
present?
1/4
Which of the following statements concerning the following equation is correct?
Reduction in heterozygosity over time depends on population size.
In a world of no inbreeding, how many ancestors would you have when Shakespeare was
presumably born (*1564) assuming a human generation time of possible 20 years. Approximately
Step 1: Determine the number of generations
• Generation time: 20 years
• Time from 1564 to 2024: 460 years
• Number of generations:
Ancestors at n = 2^n
8 x 10^6
Which statement concerning the ancestral recombination graph is incorrect?
A) Recombination introduces a change in the genealogy.
B ) If recombination rate exceeds mutation rate inference on the undertying genealogy is no longer possible well. ~
C) Genealogies change abruptly at recombination breakpoints.
D) The ancestral recombination graph applies to all sexually reproducing, outcrossing species
E) Identity by descent can no longer be establishe
E)
